drm_crtc_load_gamma_888(9)

📦 version 7.3.1, in nixpkgs unstable

💖 drm_crtc_load_gamma_888 — kernel API manual, but make it cute 💖

ok so this is the drm_crtc_load_gamma_888(9) page from the Kernel API Manual and bestie, it's literally about pushing a gamma ramp into hardware. short page, but every word slays. let's go 🎀

✨ NAME ✨

drm_crtc_load_gamma_888 — programs the gamma ramp for RGB888-like formats. that's it, that's the whole job 💅

🌸 SYNOPSIS 🌸

void drm_crtc_load_gamma_888 (struct drm_crtc *crtc , const struct
drm_color_lut *lut , drm_crtc_set_lut_func set_gamma );

like, three args, one void, no drama. iconic behavior honestly 🫶

🦋 ARGUMENTS 🦋

  • crtc — the displaying CRTC. the main character screen-energy one 👑
  • lut — the gamma ramp you're about to program. the actual color vibes 🌈
  • set_gamma — callback for programming the hardware gamma LUT. the lil function that does the actual touching of hardware, iykyk 🔥

💜 DESCRIPTION 💜

so what does it do? it programs the gamma ramp you passed in lut straight into hardware. simple, clean, no cap ✨

the one rule tho: the input gamma ramp must have 256 entries per color component. not 255, not "eh close enough" — 256. every single color component. fr fr, don't play with it 😭

💀 reminder bestie: drm_crtc_load_gamma_888(9) does not have its own NOTES, RETURN VALUE, ERRORS or COPYRIGHT section on this page. what you see is what you get. don't invent lore ✨

ok bye ily, this page lives in ./drivers/gpu/drm, it's dated October 2026, and it comes to you from the Kernel API Manual — mwah, go program some gamma ramps responsibly 💖🎀💅
